FFtCE I COTTON-CROP 'SEPARATOR. 1

To dZZ "LOZL'OWL itimay' concern:

-"Betit' known that I, l/VENSE LTNIORAYA, a citizen of the United "States, and a 2resident of the 'city'of Chicago, in the county of Cook and-"refuse and for'like use' in respect to any other similarlyconditioned material of whicha-ip'art is adapted to roll downian inclined surface while the remainder is not thus adapted. It consists in' the elements and features of construction shown and de scribed, as indicated in the claims. In the drawings: V Figure 1 is an end elevation of an ratus embodying this invention.

Figure 2 is a front elevation of the same. Figure3 is a plan view of the'same. I 'Figured is a! rear side elevation of'the ame, H :'1

The construction shown in the drawings comprises supporting frame work, (which may be in part the frame structure of the building in which the apparatus is contained), represented by upright posts, 1, overhead and transverse and longitudinal frame members, 2 and 3, with suitable bracing members, 4. From this supporting frame structure there is suspended by suspending bars, 5, 5, at the higher side and by extensible and contractible suspending links, 6, 6, at the lower side, an inclined end less conveyer frame, 7, in which there are journaled the shafts, 9 and 10, of the driving and idler rollers, 11 and 12, of an out less conveyor belt 13; andextending along the lower side of said conveyor belt this frame carries a receiving trough, 14, in which there is located a spiralconveyor, l5, rotated as hereinafter described for propelling the material which may be delivered into it from the inclined conveyor, for dis charge at one end of said trough. 16 is a shaft journaled upon the main supporting structure which comprises the upright posts, 1. extending along the higher side of the conveyor, having near its opposite ends eccentrics, 17, 17 which are connected by the ppa I Specification of Letters Patent.

eccentric .pitman links," 18,18, with the conveyor frame for oscillating said frame? back and *forth transversely of the direction "of travel of the c0nveyo1,'f0r'- giving a joggli-ng "or jarring movement to the material lying upon 'th'e' inclined surface of the conveyor 1 belt during the travel-in thedirectiontrans- -verse-to said Ejarringzmovement. 20 is a hop- 1 peroverhanging the entrance end of theconveyor belt "at the higher side thereof, into which a chute, 21%; discharges for delivering onto the-'beltthe' material t0-be separated,

said-material consisting of the cotton crop as, taken from the. cotton-plant'bodily, comprising opened and unopened'bolls, twigs,

leaves and the like, from which the unopened bolls :which are still in condition sufficiently nearly round to roll' down the slight incline, are tobe separated while the Linaterial is being carried by the conveyer.

25 is an overhead xco untershaft j'ournaled' in bearings, 26, 26, mounted upon the over-. head portion of the main supporting struc-' -ture. The shaft, 25, carries two;v 'wheels, '28 and 29.

driving F romthe wheel, 28, a

f drive belt, '30, extends around a drivenwheel, "31,. on the shaft, '19, foractuating'thecendlessTi-belt' conve'yer by '1Tl6II1S -Of thebevel gears, 22:and 28,-on the shafts, 19 and 9, :re-

spectively. From the wheel, 29, a driving belt, 35, extends about aidriven wheel, 36, on the shaft, 16, having the eccentrics, 17, for oscillating and agitating the conveyer as, already described.

The relative size of the power-transmit ting wheel for'driving'the conveyor and for agitating it are such as to give any desired rapidity of agitation relative to the speed of travel of the conveyerbelt; and these relations will be determined by experience with the various material and various conditions of material operated upon; but, in

general, it is consideredthat the conveyor belt travel is comparatively slow and that themovement of agitation is rapid enough to give what may be called a jerky movement to the conveyer for the purpose of starting the rolling of any bolls which may be partly opened or otherwise irregular so as not to roll easily, but not abrupt enough to cause any substantial sliding of the material which is not adapted to roll, as the twigs and leaves and fully opened bolls, it being designed that this latter class of mat-erial shall be carried by, the conveyer over its entire path of travel and delivered at the ducted to an apparatus for ripening and further treating them.

It will be recognized that the relation between the angle of inclination or slope of the conveyer, and the rapidity of the joggling or jarring. movement which the c0nveyer receives may require variation according to the varied condition of the material.

-This variation may be effected by varying either the speed of the jarring movement or the inclination ofthe conveyer. In the construction shown, provision is made for varying the latter, as being more easily provided for than the variation of speed of the joggling movement. clination of the conveyer, suspending links, 6, 6, which uphold its lower side are made adjustable by turn-buckles, 6 with which they are each provided.

I claim 1. In an apparatus for the purpose indicated in combination with a frame, a driving and an idle roller and an endless carrier carried thereby; a rotation-modifying train anterior to and actuating. the driving roller, said train having its several shafts and wheels journaled in said frame; a belt- For varying the inactuated wheel on the prime shaft of said train; means for movably upholding said 40 frame at its upper and lower side respectively, said means being adapted for swinging movement of said frames bodily substantially parallel to the plane of the beltactuated wheel, and means for vibrating said frame bodily horizontally in the general direction of said frame.

2. In a construction for the purpose indi-' cated in combination with 'a frame, a driving and an idle roller and an endless carrier carried thereby; an actuating gear train for the driving roller having its several shafts and wheels journaled in said frame; a beltactuatedwheel on the prime shaft of said train; means for suspending said frame at one side, and means for supporting itmovably at the opposite side, both of saidsuspending'andsupporting means being adapted for swinging 1 movement, of said frame bodily substantially parallel to the plane of the belt-actuated wheel, and means for vibrating said frame bodily horizontally in the general'direction of saidplane;

3. In the construction defined inclaim 1,

means for supporting the frame ofsaid end- .65

less carrier at one side so as to be movable bodily transverselyjof the carrying move-f ment of the carrier, carrier-actuating means at that side, means for suspending the frame at the opposite side and means for adjusting the suspending means to vary the transverse inclination of the carrier. 7 V In testimony whereof, I have hereunto set my hand at Chicago, Illinois, this 6th day of August, 1920. s WENSEL MORAVA.
